To all whom it may concern:- trunks 4 of the Y passages in the valve; soBe-it known that I, ARCHIE N: RUTAN, a that one or the other of saidpassages will be citizen of the United States, residing at Elplaced inregister with one of said ports when niira, in the county of (.hemungand State of the valve is turned to the right or left. The V New York,have invented certain new and valve casing is also provided at 9, 9,with two useful Improvements in Valves, of-which the exhaust passages,so positioned as to be also following is a specification. in the lineoftravel of the Y passages of the This invention relates more particularlyto valve; so that'vhen one of said passages is in improvements in valvesadapted to control communication with one of the admission theadmissionto and exhaust from the oppo- .ports 8, the other passage willbe in commusite ends of the cylinders in pneumatic nication with anexhaust port 9. In the cap presses, hoists, and other fluid operated ap-I provide two diametrically opposite openpliances, wherein it isrequired to stop and ings 10, into which are screwed the pipes old apiston at any point of its travel in which lead to the opposite ends ofa cylinder either direction; and to start it again upon to control themotions of a piston contained its travel, either in the same directionin therein; or these pipes may lead to any apwhich it was going, or inthe opposite direcpliance wherein the flow of fluid is to be contion. Idonot confine myself to this use of trolled in a like manner.

This le I attain my object by constructing the veris rovided with a locking latch 15, valve 'n the manner illustrated inthe accomadapt'e to engage notches in a segment 16 on pany' g drawings,in whichthe cap 2.

V way between the admission and exhaustIn carrying out my invention I provide a ports 8 and 9, thus forming adouble shut-ofl' cylindrical valve casing 1, closed at its open betweenthe ports 1.0 and the admission and end with a cap 2. A cylindricalvalve 3 is exhaust ports 8 and 9. If, now, it is desired .100 fittedinto a corresponding chamber in the to admit the fluid to pipe 12 and toexhaust valve casing, and is free to rotate therein. from pipe 11, theoperating lever will be At diametrically opposite sides, this valve isturnedto rlic'right, thereby placing the trunk provided with twoY-shaped passages, comof'thje Y passage on the left hand side incomprising a trunk portion 4, and the two munication with the admissionport8 on said r ranc es 5 and 6, respectively. The closed side, ,thefluid passing through branch 5 to end of the valve casing is providedwith an port 10, leading to pipe 12. At the same opening ada tedto'receive thepipe 7, which amass trunk of the Y passages on the rightleads frlom time source of fluid pressure suphand'sicle will be placedin register with the Ply. This opening is preferably at the cenexhaustport 9 on said side, and branch 5 will 11 816 ter, and frornlitlead twopassages 8, 8, to register with the right hand port 10. By

ports positioned on the line of travel of the r cation alternately witht respective Y passages, and saidports and passage 9 on the left handside, and the pipe 11 in communication with the admission port 8 on theright hand side. By setting the I valve in intermediate positions theadmission and exhaust will be correspondingly adjusted and controlled.The valve seats against the closed end of the casing and also againstthe cap, thereby rendering-it impossible for the admission and exhaustto pass by leakage from one side of the valve to the other.

What I claim as my invention and desire to secure by Letters Patentis 1. A cylindrical valve having two longitudinal Y-shaped passages, incombination with a chamber in which the valve is revolubly mounted, saidchamber being provided at one "end with admission and exhaust portsadapted to be placed alternately in communication with the trunks of therespective Y passages, and at the other end with two ports each adaptedto be laced in communication alternately with t e branches of therespective Y passages.

2. A cylindrical valve having two longitudinal Y shaped passa es, incombination with a chamber in whie the valve is revolubly mounted, saidchamber being provided at one end with admission and exhaust portsadapted to be laced'alternately in communication with t e trunks oftherespective Y.

passages, and at the other end with two ports each adapted to be %lacedin communie branches of the passages being so positioned relatively toone another, that, when the valve is in closed position, the trunk ofeach Y passage will lie cylindrical valve fitted to turn in the (Illa-HPber and provided with two oppositely di posed longitudinal Y-shapedpassages, the

'trunk ortions of said )assa es hem )ositioned in the same circle withthe admission and exhaust ports aforesaid and each adapt- .ed to liebetween an admission and an .ex

haust port when the valve is in closed position, a cap to close thechamber, said cap forming a seat for the outward. end of the valve andbeing provided with two opposit ily disposed ports and passages, saidports being each positioned between the branches of a Y passage throughthe valve, when the valve is in closed position, whereby said cap' ports.may be placed alternately in eomnn1- nication the one with theadmission-ainl the other with the exhaust as the valve is turned in onedirection or the other, and the valve stem passing through the cap andprovided with an operating lever.

In testimony whereof I have allixed my signature, in presence of twowitnesses.
